Its always a good thing to know the wheel, but betting 3 numbers doesn`t require to know the wheel, you simply read the numbers at the number ring when you read your prediction. 5 numbers is a bit more diffycult, then you need to know the sectors by heart.

The biggest problem as i see it, is not to memorize the numbers, but to place the high numbers at 30 - 36 without knocking the old chinese woman located next to you down, when you are standing at near the top where you can see the wheel properly. Also, the arms are simply too short so one will have throw the chip the last 20 - 30 centimeters which sometimes results in a split or corner bet even though it should have been a single number.

Reading numbers on the ring is fine but it assumes that your betting number is the same as the reference number that you calculate as you do your vb. Sometimes for examlpe you might be monitoring for a wheel speed that results in your betting number being say oppoite the reference number. Its a waste of time to continue to observe the wheel to guage the opposite number and it neigbours. If you know the wheel intimately then you can be calculating the betting numbers after your eyes leave the wheelring and as your leaning over to place some bets.

This is much more efficient and reduces the time that you're staring at the wheel. It also means that you can bet a 5 or 7 number sector if you wish.

Fair point Kelly - its all in the training! I try to leave as little to 'estimation' or visual cues as possible, that way i hope to leave more energy/time etc for the most difficult parts of the process. But what your saying that you do really is almost instantaneous anyway i suppose.

If you're betting on three numbers then if your flatbetting, you need to win an average of 1 of every 11 spins that you bet on to be ahead over the long run. Interesting. How did you choose three as the sector size?

oh i didn`t mean to imply that i was always betting 3 numbers, it all depends. If my analyse shows the highest standard deviation and best return on a 5 or 7 number sector, thats what i go for. On the other hand, if the layout has no racetrack and the dealers don`t offer to place the bets for me, i bet 3 numbers or if 5 or 7, then as many as i can get away with before the dealer whack my fingers or gets annoyed with me. Usually that cuts the placed numbers down to 3 - 4 numbers.

The hit rate on a 3 number bet, divertes a lot. Its best suited for a long term play where your intention is to play 75 - 100 or even more spins after your tracking. Otherwise you might fall out between bad scatter streaks, but if you play 100 spins or more and have the bets in the correct place, the edge will usually show sooner or later. 50 - 100 unit bankroll can easyli be the standard to cover bad scatter, depending on the diffyculty of the wheel.

If the intention is to only play 30 - 40 spins, 7 - 9 numbers are better. Or at least 5 numbers. That way you will cover many of the bad scatters too, and you can leave after say, 8 - 10 hits playing a 9 number sector. Or whenever you hit +100 units, whatever comes first.
